Arduino CO2 and Temperature Logger Based on BOSCH BME280 and Winsen MH-Z19B This project showcases a cutting-edge Arduino-based logger that measures CO2, temperature, humidity, and pressure levels. The device utilizes the renowned BOSCH BME280 sensor for accurate readings of temperature and humidity, while the Winsen MH-Z19B sensor provides precise CO2 measurements. Key Features: * Displays real-time readings of CO2, temperature, humidity, and pressure levels * Allows users to correct temperature and humidity readings if the BME280 is out of calibration * Seamlessly integrates with Thingspeak for WiFi connectivity and data logging To replicate this project, please visit the GitHub repository which includes detailed schematics, Arduino code, and design files: [GitHub Repository](https://github.com/XylenC4/CO2-ESP32) Required Components: * 1 x BOSCH BME280: Available on Aliexpress at [BMP280 Link](https://www.aliexpress.com/wholesale?SearchText=bmp280) * 1 x OLED Display: Connect to I2C pins and available on Aliexpress at [OLED Link](https://www.aliexpress.com/wholesale?SearchText=oled+i2c) * 3 x TTP223 Capacitive Touch Sensors: Available on Aliexpress at [TTP223 Link](https://www.aliexpress.com/wholesale?SearchText=HAILANGNIAO+TTP223) * 1 x Winsen MH-Z19B CO2 Sensor: Available on Aliexpress at [MH-Z19B Link](https://www.aliexpress.com/wholesale?SearchText=MH-Z19B) * 1 x 30mm Silent Fan: Available on Aliexpress at [Fan Link](https://www.aliexpress.com/wholesale?SearchText=30mm+fan+5v+silent)
